Title: System and method for assiging electronic dictionary
Inventor: AOE JUNICHI
IPC: G06F17/27
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to assist various operations for generating an electronic dictionary, by showing information needed to generate the electronic dictionary, i.e., information regarding the use frequencies and examples of respective words of a document. SOLUTION: A document registering means 1 hierarchically classifies and registers documents, which are already published, according to proper parameters corresponding to their sources. A morpheme analyzing means 2 decomposes a registered document into words and converts the document into a sequence of morphemes consisting of word notation and parts of speech. A frequency totalizing means 3 totalizes the appearance frequencies of the morphemes of the registered document according to the analytic result of the morpheme analyzing means 2 by using the classification reference parameters of the document registering means 1 as units. An example display means 4 displays sentences before and after the morphemes so that how each specified morpheme is used in the actual document, can be found. Consequently, a proper example can be shown to a dictionary producer as the producer only desires.

Abstract: PURPOSE:To obtain the title apparatus capable of outputting the accurate particle size value of particles to be measured even when said particles do not correctly pass through a measuring visual field, by calculating the particles size of the particles to be measured from the rising time of a scattering light pulse signal. CONSTITUTION:An operation apparatus 13 calculates the peak value Imax of the scattering light pulse signal S read from a waveform memory apparatus 12 from the data thereof and calculates, for example, the preset points X1, X2 where the 90%- and 10%-threshold values of the value Imax cross each other and the rising time Dw' of the signal S wherein both points are connected by a straight line is calculated by extrapolation. Next, an actual rising time Dw is obtained according to a predetermined formula to set a 50% threshold value to the value Imax and points X3, X4 where the value of the signal crosses said threshold value is calculated to calculate the time tv between them. The passing speed (v) of particles M to be measured is calculated based upon the length Iz of a preliminarily known measuring visual field E and the time tv. Next, the speed (v) and the time Dw are used to calculate the particle size of the particles according to a separate predetermined formula to display the same on a display device 14. Thereby a particle size can be measured with respect to all of the cases wherein the particles M pass in such a state that 1/2 or more of the sizes thereof enters the visual field.

Abstract: PURPOSE:To stabilize the operation of a condensing heat exchanger, by arranging an evaporation preventing plate between the inside wall of a refrigerant tank and the liquid surface of refrigerant, and lessenig the fluctuation of the internal pressure of the refrigerant tank due to oscillation. CONSTITUTION:An evaporation preventing plate 9 made of a light and high heat conductive material covers the upper half of a refrigerant tank 4, and its lower edge is soaked in refrigerant 3. Then, the whole evaporation preventing plate 9 is kept at a refrigerant temperature.

But, even if a liquid drop of the refrigerant 3 spatters on the evaporation preventing plate 9, rapid evaporation does not occur, because the evaporation prevention plate 9 is cooled. Accordingly, the fluctuation of internal pressure of the refrigerant tank 4 lessens, and then, the operation of a condensing heat exchanger is stabilized.

Filed: 1988-03-30
Abstract: PURPOSE:To make a photocurrents hardly flow through a light-receiving section not irradiated with light by forming a semi-insulating polycrystalline silicon film on one part of the surface of a first conductivity type semiconductor substrate between second conductivity type regions. CONSTITUTION:When light 20 is projected to an anode 11, holes generated in an N<-> semiconductor substrate as a cathode 5 reach into a P<+> diffusion layer as the anode 11 by a diffusion, and are changed into photocurrents. Consequently, holes generated also move toward a P<+> diffusion layer as an anode 12 because the diffusion is conducted in an isotropic manner, but the greater part of holes reach onto the surface of a semi-insulating polycrystalline silicon film 4 because the film 4 is shaped near the midway reaching to the anode 12, are coupled with electrons on the surface of the film 4 and disappear, and do not reach to the anode 12 approximately. Accordingly, photocurrents generated by the incidence of light 20 into the anode 11 hardly flow through the anode 12.

Title: Measuring method for dissolved oxygen

IPC: G01N33/18
Filed: 1981-05-21
Abstract: PURPOSE:To measure dissolved oxygen simply, by aerating air to a liquid to be measured and measuring the concentration of oxygen of a gas after aeration. CONSTITUTION:A blastipipe 2 is provided so as to open at a suitable depth in a liquid reagent to be measured 1 and air is aerated. The concentration of oxygen of a gas after aeration is measured by an oxygen detector 3 attached to the upper part of a cylindrical vessel 4. In the case where sample water is equillibrated with oxygen in air, e.g. when the concentration of dissolved oxygen is 9.76ppm at 15 deg.C, the concentration oxygen in the air passing through the sample water is not varied and dissolved oxygen is bubbled out in a gas phase at 21% oxygen concentration after passing through the sample water. In the case where the concentration of the dissolved oxygen in the sample water is low, dissolution of oxygen is carried out at the time of passing through the sample water and dissolved oxygen is bubbled out in the oxygen concentration lower than 21%. For example, in the case where the concentration of dissolved oxygen is 4.88ppm at 15 deg., the concentration of oxygen of the gas in an equillibrium state is 10.5% and the value in accordance with the concentration is detected by a detector.
